It is now possible to create private projects. To mark a project as
private, you simply go in the Administer > Tabs Access menu and select
"Private project". Only project members and owners together with the
extra authorized users will be able to access the project. The project
will not appear in the list of projects for not authorized users.
For each tab, at the exception of the project home and the
administration area, it possible to control the access rights if the
user is anonymous, signed in, member or owner.
